COIN-CONTROLLED LOCK.

To all whom it may concern:

Be it known that I, GEORGE G. F. Bos- WELL, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Coin-Controlled Lock; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is the use of coins of difierent denominations for operating a single lock; and the chief feature of the invention consists in the arrangement whereby coins of different denominations may be employed for opening the lock, that is, with a very slight adjustment the lock may be adapted for opening by any of the small coins. I-Ieretofore it has-been necessary to provide a separate lock for each denomination of coins. With this invention it is unnecessary, as the one lock may be oper-' ated by a coin of any denomination used for operating locks. To that end the lock is provided w1th an adjustable coin holder, pref erably secured by a screw which enables the coin holder in an instant to be adjusted to suit any coin.

Another object is to prevent the bolts of coin controlled looks from being picked. This object is accomplished by having a flange extending from the lock case so as to project over or overlap the keeper into which the lock enters when the door is closed. This prevents the picking of the look by inserting an instrument between the keeper and the lock case into the lock to move and open the bolt.

Another object of the invention is to improve the mounting and mode of operation of the shutter for closing the coin slot so that it cannot be picked.

Another object is to simplify the construction and manipulation of coin controlled locks. Heretofore the locks have been formed of two or more parts including a back and with some parts of the mechanismof a lock on each part in the casing. Therefore, the portions of the casing had to be assembled and also the portions of the lock mechanism on said parts of the casing had to be brought and maintained in proper position and relation to each other. This difiiculty is overcome in this invention by mount- Speeiflcation of Letters Patent.

ing all of the lock mechanism in one casing or member of the casing, said casingbeing formed of one piece and having no back. Therefore, when the casing is taken off the door, all-of the mechanism is at once visible and accessible for any purpose and when secured on the door, the casing is closed by the door itself. A back section of the casing 1s, therefore, rendered needless and there is no mechanism of the lock mounted on the door, excepting the casing.

Another object of the invention is to improve the arrangement of the parts of the lock and render the same readily reversible to be placed at different edges of a door and on different sides of a door.

The full nature of the invention will be understood from the accompanying drawings and the. following descriptlon and claims:

In the drawings, Figure 1 is an elevation of a portion of a door and door frame with a coin controlled lock thereon and the door closed, the lock being at the left-hand edge of the door. Fig. 2 is the same with the lock reversed and placed at the right hand edge of the door. Fig. 3 is a rear elevation of the case and mechanism of the lock, parts being broken away and with the bolt shut. Fig. 4 is a section on the line 44 of Fig. 3. Fig. 5 is the same as the upper part of Fig.

3 with the bolt withdrawn. Fig. 6 is a sec-' tion on the line 66 of Fig. 5. Fig. 7 is the same as the upper part of Fig. 3 with parts removed and parts in different positions of operation. Fig. 8 is the central portion of Fig. 3, with parts omitted and parts adjusted to be operated by a ten cent piece instead of a five cent piece. Fig. 9 is the same as the upper part of Fig. 3 reversed from right to left. Fig. 10 is a section on the line 1010 of Fig. 3. Fig. 11 is a section on the line 11-11 of Fig. 3, one of the knobs being shown in section. Fig. 12 is a section on the line 1212 of Fig. 11. Fig. 13- is a section similar to that in Fi 10, but of a modified form, putting'the ange on the keeper instead of on the lock case..

There is shown in the drawings in Fig. 1 a door 10 with a lock on the left-hand'edge thereof engaging a keeper 11 on part of the door frame 12. In Fig. 2 the lock is atthe right-hand edge of the door instead of the left. The lock casing 13 consists of a single case forming the front, sides and top and Patented June 12, 1917.

in a casing so that when the casing is removed, all of the lock mechanism is mounted in connection withthat one part of the easing instead of being mounted on a plurality of parts of the casing, asheretofo're. This enables the lock mechanism to be rigidly mounted and be accessible for repairs or manipulation. When different parts of the mechanism are mounted on different parts of the casing there is difiiculty in bringing said parts of the casing in proper operative relationship when the parts of the casing are united. This obviates this difliculty.

The casing has an operative flange 14 on both sides thereof which surrounds, envele ops and overlaps the inner end of the keeper so that when the door is closed and looked, a person cannot insert any instrument between the keeper' and the case and thus get into the lock and move the bolt to open the same. The flanges on both sides enable the casing to cooperate with the keeper and to accomplish this end whenever the lock is reversed regardless of the position in which' it may be mounted. A modified form is shown in Fig. 13 where there is a flange 15 on the outer portion of the keeper '12 instead of a flange being located on the outer part of the casing. But in such construction there is still the upper and lower flanges left on the case. The purpose of this construction is toadapt the lock to the door if it swings inwardly. The construction previously described and shown in Fig. 1 is adapted for a door which swings outward. It is immaterial whether the flange 14 for protecting the look from picking projects be yond the main surface of the case or not so long as there is a surface of the case which overlaps the keeper.

The case has a counter slot 16 in its upper end, a coin inlet slot 17 below it, a porter key hole 18, an outside knob 19, a removable door 20 and the coin chamber, as shown in Fig. 1.

There is shown in Fig. 10 a bolt 25 which has a vertical and longitudinal slotted portion extending almost to each end thereof and wide enough to receive any of the small coins. The bolt is 'slidable transversely of the .casing between the two guide ribs 27 and 28 which extend entirely across the inner surface of the front wall of the casing. On each side of said bolt there are two flanges 30 and 31 and said flanges on the two sides of the bolt are opposite each other respectively, as shown in Fig. 10. The rear flanges 30 have each a hole through which a guide rod 32 loosely projects. Said rod is connected with a plate 33 loosely located in a bolt opening 34 and is held in said openplate 35 slides into the flange 14 on the rear side of the case, the inner surface of said flange being dovetailed and the flange forms three sides of a rectangle and the open'side next to the doorthrough which said plate- 35 can be slipped in and out when the casing is removed from the door. A spiral spring 36 surrounds the rod 32 and bears against the flange 30 for throwing the bolt and holding it in looking position. Said spring is compressed when the bolt is retracted. Both flanges 30 have a hole in them to receive said rod 32 so that the bolt can be reversed, as shown in Fig. 13, depending upon whether the door is to move outward, as shown in Fig. 10, or to move inward, as shown in Fig. 13.

The bolt.is retracted by the turning of the knob 19 and a shaft 38 and a finger 39 which is rigidly secured thereon. Said finger when given revoluble movement in one direction engages a projection 40, see Fig. 6, from a coin actuating bar 41. This barhas two similarly. formed ends and midway it is rigidly secured to a rod 42 which extends transversely of the construction and theguideways '43 in the rear edges of a pair of plates 44 which extend vertically rearward from the inner surface of the case. A spiral spring 45 surrounds said rod and lies between the left-hand plate 44 and a connection 46 between said rods 42 and the coin i actuating bar 41, for the purpose of. returning said bar to its normal position after it had been actuated for operating the door knob.

The coin which is inserted in the coin inlet slot 17 enters a coin chute formed by the front wall of the case and twovertical walls 47 extending from said case and a re movable plate 48 secured to the rear of said walls 47. This makes a chute relatively large at the upper end and tapering outwardly to the slot 26, in the bolt, as seen in Fig. 4., The coin enters said slot in-the bolt by gravity, but cannot pass through the slot untll permitted by the proper operation of the mechanism. The coin lodges in the slot in the bolt against the coin actuating bar 41 on the right hand side, as seen in Fig. 3, and there is a lug '49 closing the left hand end of the slot 26. This lug or abutment 49 is fixed. 'The end of the coin actuating bar 41 is notched so as to have a lower shoulder 141 to stop the progress of the coin and an upper shoulder 241 which projects above the center of the coin so when the plate 41 is open the door. When the knob and knob shaft are operated, the bar 41 has slidable movement from the left to the position lee shownin Fig. 3 and in such movement compresses the spring 45. opened and the knob released, said spring will return the bar 41 to normal position, but

at the same time the bolt spring 36 will move the bolt to its outward position and thus the coin will be held still in the bolt and not dis charged although the door is open.

The coin is discharged when the door is being shut after the door has been closed. When the door is being closed the bevel end of the bolt will engage the keeper so that the keeper will force thebolt inward and since in that instance there is no movemergt of bar 41, the abutment 49 will be moved away from the coin and the coin will descend into the lower part or box in the case.

To adapt the lock to coins of varying sizes, it is only necessary to adjust the position of the coin actuating bar 41' with reference to the abutment or lug 49. This is done by a screw 50 in the end of the rod 42 and abutting against one side of the case, as shown in Fig. 3. Thus in Fig. 3, the adjustment is such as to enable the lock to be opened by a five cent piece. In Fig. 8, the

adjustment adapts the lock to be operated by a ten cent piece. As seen in Fig. 8, the screw has been operated, so as to push the plate 41 over fa-rthertoward the abutment 49. In this way by turning the screw 50, the device can be adapted in a minute to any desired denomination or coin.

--It is also to be noted that both ends of the bar 41 are similarly formed so that it can be reversed in position by merely lifting the rod 42 out of place and turning it from the position shown in Fig. 3 to that shown in Fig. 9. The bolt is covered and protected on the rear by a plate 51 which is removably secured in place by screws 52 and said plate holds the rod 42 loosely in place on the plate 44 of the casing.

The shutter mechanism is constructed and arranged to operate as follows: Referring to Fig. 4, there is a transversely extending shutter plate 60 with an upwardly projecting shutter 61 with a vertical concave outer surface. When the shutter is in the position shown in Fig. 4, the coin inlet slot 17 is opened. When the shutter is in the position shown in Fig.6, said inlet is closed. The shutter plate is vertically oscillatory and, therefore, is fulcrumed on a horizontal rod 62 extending transversely of the casing and secured at its ends by screws 63. Said fulcrum rod 62 is between the ends of the plate 60 and the plate is actuated by the depression of the rear end of a round headed screw 64 in the upper transverse member of a shutter actuating frame 65. This frame 65 is laterally slidable and when in the position shown in Fig. 5, the rounded lower end of the screw 64 lies to one side of the shutter plate 60 out of engagement therewith.

After the door is When, however, said shutter actuating frame is moved to' the right, as in Fig. 7 the rounded lower end of the screw 64 will engage the rear end of the shutter plate 60 and actuate the shutter plate 60 from the closed position shown in Fig. 6 to the open position shown in Fig. 4. When the frame 65 is moved back to the left, as shown in Flg. 5, and the screw 64 disengages the plate 60, the shutter will be moved by gravity to the closing position shown in Fig. 6, which Wlll prevent the introduction of a coin until the lock is further operated. The shutter actuating frame is supported and 1s laterally slidable on the shutter'fulcrum rod 62 and it has two downwardly extendlng arms, one at the left-and one at the right. The lower end of the left-hand arm is in position to be engaged by the coin 66 when it is moved to retract the bolt and open the door. Therefore, the lower end of the left-hand arm extends into the slot 26. The rlght hand end arm also projects into said slot in position to be engaged by an oscillatory plate 68 which is rigidly secured on a shaft 69 of an inside knob 70 of the door. This plate 68 is shown in Figs. 5 and 7. When the inside knob is operated so as to turn plate 68 from the position shown in Fig. 1 to the position shown in Fig. 5, said plate 68 will throw the shutter actuating frame to the right, as shown in Fig. 7, and open the shutter, as shown in Fig. 4. Hence, the shutters will remain closed while a person is in a booth or the like and will prevent the introduction of any coin from the outside until the person operates the inside knob to open the door. This shutter remains open until another.c0in is inserted and when the door is opened through the instrumentality of said coin, the shutter actuating frame is moved from the position shown in Fig. 5 by the coin and the shutter will be again closed. Said shutter acts also as an indicator for showing to a person outside that there is a person inside. At the upper end of the case there is a counter 7 3 which is visible through the counter slot 16 and has a downwardly extending shaft 74 with an arm 75 thereon having its ends slotted to receive a pin 76 extending up from the shutter actuating frame 65. Therefore, the counter is operated every time the shutter is closed. The outer surface of the shutter 61 is vertically concave so as to render the picking of the lock at that point impossible while another person is inside the booth or the compartment closed by the door. Often the plain shutters heretofore in use can be opened by manipulation of a coin in the coin slot and this often occurs by persons who are innocent and ignorant of the proper operation of the lock and door.

The inside knob 70 is preferably formed and secured as shown in Fig. 11, by means of screws 80 which screw from the other side of the door into the knob base so that the screws cannot be operated from the outside and the heads of the screws are counter sunk in the door and plugged. These screws are covered by the lock case.
